From: Rashika Date: Thu, 31 Oct 2013 11:20:42 +0000 (+0530) Subject: btrfs: Remove useless variable in write_ctree_super() X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=f570e757b54ca6eceabc9b19a6342f14e836c196;p=openwrt%2Fstaging%2Fblogic.git btrfs: Remove useless variable in write_ctree_super() The function write_ctree_super() in disk-io.c uses variable ret to return the result of function write_all_supers(). Since, this variable serves no purpose, hence the patch removes it and returns the call of the called function.
